Chief Cabinet Secretary Yoshihide Suga says the government plans to offer assistance to a Japanese man who was sentenced to 15 years in prison in China for spying.
Suga addressed the issue at a news conference on Tuesday. The man in his 50s was detained in China after conducting surveys for hot spring development.
Suga said government officials are still trying to confirm the details, and refrained from commenting as the legal process is ongoing.
He said the government will continue to offer as much assistance as possible in light of protecting a Japanese citizen.
A number of Japanese have been detained in China since 2015, one year after the country's anti-espionage law took effect. Seven of them have been sentenced to prison. The latest sentence of 15 years is the harshest so far.
